Abstract: A method performed by a base station may include transmitting a configuration message including at least information indicating a subset of a plurality of transmit beams to be used for transmitting a set of synchronization signals. The set of synchronization signals including a primary synchronization signal and a secondary synchronization signal may be transmitted. A random access channel (RACH) transmission may be received using a receive beam associated with one of the subset of the plurality of transmit beams used by the base station to transmit the set of synchronization signals. The transmitted set of synchronization signals transmitted may have a signal quality above a signal quality threshold. A reference signal may be transmitted along with a physical broadcast channel (PBCH) transmission. The reference signal may have a sequence derived from a beam index associated with the one of the subset of the plurality of transmit beams.

Abstract: Methods and apparatus for initial cell search and selection using beamforming are described. An apparatus is configured with multiple receive beams and includes an antenna and a processor. The processor is operatively coupled to the antenna and sweeps a respective one of the multiple receive beams during each of multiple synchronization sub-frames, using a pre-defined sweep time and dwell period, to detect a synchronization signal. The processor also obtains symbol timing information and a synchronization signal index from the detected synchronization signal. The obtained synchronization signal index corresponds to a synchronization signal index of the set. The process decodes a first broadcast channel using the obtained symbol timing information, the obtained synchronization signal index and a predefined or blind-coded symbol distance between the detected synchronization signal and the first broadcast channel. The process decodes a second broadcast channel using information obtained from decoding the first broadcast channel.

Abstract: Methods are described for performing joint coded spatial and/or antenna based modulation. A first device may receive, from a second device, one or more pilot signals associated with one or more transmit antennas, antenna patterns, and/or antenna polarizations. The first device may determine channel related information associated with an antenna pair based on the pilot signals. The channel related information may include one or more channel cross correlation coefficients. The first device may determine a set-partition, for example, based on the channel related information. The first device may configure a dynamically configurable Trellis Coded Modulation (TCM) decoder based on the determined set-partition.

Abstract: Systems and methods related to increased spectrum efficiency for 5G communications, comprising combining time, frequency, spatial, and signal domains for multi-dimension modulation. In one embodiment, the ability of reconfigurable antenna to change their radiation pattern and/or polarization modes may be used to modulate additional information onto the conventional SM-MIMO transmitted signal. In further embodiments, various combinations of space shift keying, block coding, multi-carrier modulation, and the like may be used to introduce additional dimensions for data modulation and achieve diversity gain.

Abstract: Systems and methods described herein are provided for radiation pattern and modulation (RPM) based on channel-state information (CSI). The method may comprise receiving a set of bits; dividing the set of bits into at least three groups, wherein at least one group is size limited by a diversity order and selection factor applied by a CSI controller; mapping the groups to distinct control signals; generating a modulated RF signal and selecting at least one configurable antenna and a configuration of said at least one antenna based on the control signals; and transmitting the modulated RF signal through the at least one configured antenna.

Abstract: A method and apparatus are disclosed for demodulating a NR-PBCH signal. The method may comprise receiving a primary SS and an SSS. The received SSS signal may be used as a reference signal to detect demodulation reference signals of the NR-PBCH. These demodulation reference signals may be interleaved with data on the NR-PBCH. In one method, the NR-PBCH DMRS are associated with an SSB index in an effort to improve randomization in the synchronization process. The NR-PBCH payload may be demodulated using the PSS and/or SSS and the DMRS. In one embodiment, the NR-PBCH DMRS may mapped to DMRS REs on a frequency first and time second mapping basis.
